NUT-LOCK. l

Specification of Letters Patent.

Application filed May 13, 1911.

Patented Dec. 10, 1912. Serial N 0. 626,881.

. To all whom it may concern:

Be it known that I, HOMER F. CRooKnn, a citizen of the United States,residing at Chillicothe, in the county of Ross and State of Ohio, haveinvented new and useful Improvements in N ut-Locks, of which thefollowing is a specification.

This invention relates to improvements in devices whereby a nut may besustained upon a bolt or a bolt sustained upon a nut, and the object ofthe invention is to provide a device of this character which is of anextremely simple construction, which is cheaply manufactured, and whichwill perform the function for which it is devised with ease and withaccuracy.

With the above objects in view, the invention resides in the novelconstruction and arrangement of parts hereinafter fully described andclaimed.

In the drawings accompanying this specification,Figure 1 is aperspective view of a device constructed in accordance with the presentinvention, and showing a nut pro vided with means for locking the boltthereon. Fig. 2 is a central longitudinal sectional view of the same.

Referring to the drawings the numeral 1 designates a bolt. This bolt isof the ordinary construction excepting that it has its outer end or faceprovided with a depression or pocket 2.

The numeral 3 designates the nut for the bolt. This nut is of that classcommonly known as carriage nuts, the same having a threaded bore whichdoes not extend entirely through the nut. The closed end or face of thenut is provided with an opening 4, the said opening being adapted toreceive the inwardly projecting sustaining finger 5 provided upon thelocking element 6. This locking element is constructed of a singleflattened strip of resilient material, the finger of the same beingformed by bending the said strip downwardly at the central portion ofthe strip. The finger thus provides a pair of oppositely arrangedintegrally formed arms, and these arms are bent in opposite directionsin a plane parallel with the outer face of the nut. These extendingportions are further bent and continued along the opposite sides of thenut and the extremities of the said extensions are bent inwardly andadapted to be received in rectangular slots 7 formed in the oppositeface of the nut.

It is, of course, obvious that the device can be applied to nutsprovided with more or less than four faces if desired.

Having thus fully described the said invention, What I claim is Incombination with a bolt having a longitudinal angular opening, of a'nutfor the bolt having a closed face formed with a substantiallyrectangular slot in the center thereof, said nut having a threaded boreadapted to receive an exteriorly threaded portion of the bolt, a lockingelement for the bolt and the nut, said locking element comprising amember constructed of a single piece of resilient material, said lockingmember being centrally formed with a finger, the said finger beingformed by bending the strip downwardly and upon itself from its centralpoint and comprising a pair of 0p positely arranged, integrally formedresilient arms adapted to enter the rectangular slot in the closed faceof the nut and the opening of the bolt and to be yieldingly retainedtherein, the said member being continued in opposite directions over theface of the nut and having its sides bent downwardly and in parallelrelation with the said finger to contact with the opposite sides of thenut, and the extremities of the downwardly extending portions of thelocking element being inturned to provide angular fingers forinterlocking engagement with the nut.

In testimony whereof I afiix my signature in presence of two witnesses.

HOMER F. OROC-KER.
